[0003] Most of the laser scanning devices in the prior art are intelligent laser scanning devices. However, when the intelligent laser scanning devices are used in hot weather, due to the small internal space of the equipment, the laser scanning devices will generate a lot of heat when measuring the building structure, causing the equipment to overheat, thereby causing the internal electronic components of the equipment to be damaged due to overheating. Summary of the invention

[0004] The purpose of the present invention is to provide an intelligent laser scanning device for building structure surveying and mapping, which effectively solves the problem that when the intelligent laser scanning device is used in hot weather, due to the small internal space of the device, the laser scanning device will generate a lot of heat when measuring the building structure, causing the device to overheat, thereby causing the electronic components inside the device to be damaged due to overheating.

[0005] To achieve the above purpose, the present invention is implemented through the following technical solutions: an intelligent laser scanning device for architectural structure surveying and mapping, comprising a positioning block, a hinged block arranged outside the positioning block is movably connected with a triangular bracket, an adjusting motor is fixedly connected to the inner side of the positioning block, an output end of the adjusting motor is fixedly connected with a fixing block, an installation box is fixedly connected to the upper surface of the fixing block, a scanner box is arranged inside the installation box, a laser scanner is fixedly connected to the front of the scanner box, a heat dissipation mechanism is arranged inside the installation box, a heat absorbing fin is arranged inside the scanner box, and an exhaust hole is arranged on the left side of the scanner box; The heat dissipation mechanism comprises a driving motor, a driving rod, a switching assembly, a driving wheel, a transmission belt, a mounting tube, a positioning frame 1, a rotating shaft 1, a driven wheel, a fan blade 1, a dust removal assembly and an adjusting assembly.

At the same time, with the use of heat-absorbing fins, the air contact area is increased, thereby improving the air flow effect inside the scanner box, thereby improving the heat dissipation effect.

[0007] Preferably, the switching assembly includes a switching slot, a switching tube, a driving block 1, a driving block 2, a rotating rod, a positioning slot, a driving lever and an electric telescopic rod, a switching slot is provided at the left end of the driving rod, a switching tube is movably connected to the outer side of the driving rod, driving block 1 and driving block 2 are respectively fixedly connected to the inner walls at the left and right ends of the switching tube, a through hole provided in the installation box is movably connected to the rotating rod, and the left end of the rotating rod is fixedly connected to the right surface of the scanner box, a positioning slot is provided at the right end of the rotating rod, the outer side of the switching tube is movably connected to the driving lever through a groove, the right side of the top end of the driving lever is fixedly connected to the electric telescopic rod, and the electric telescopic rod is fixedly connected to the inner wall of the installation box.

[0012] Through the above technical solution, the adjustment component of the present application rotates the steering motor to adjust the air outlet angle of the air outlet duct, so that the air can blow directly to the heat source and cover a larger area, thereby improving the heat dissipation effect and avoiding the situation where the air duct blows in the same direction, thereby reducing the heat dissipation effect.

[0017] By adopting the above technical solution, the beneficial effects of the present invention are: 1. The intelligent laser scanning equipment used for building structure surveying and mapping increases the air flow rate inside the scanner box by setting a heat dissipation mechanism, and at the same time cooperates with the heat-absorbing fins set inside the scanner box to concentrate the heat inside the scanner box on the heat-absorbing fins. When the flowing air contacts the heat, the heat is taken away by heat exchange, thereby achieving a heat dissipation effect and avoiding the situation where the temperature inside the scanner box is too high and the electronic components are damaged.

[0018] 2.

The scanner box 6 is provided with a sealing groove 8121, and a sealing plate 8122 is movably connected inside the sealing groove 8121. The groove provided in the sealing plate 8122 is connected to the mounting tube 86. One end of the connecting hose 8123 is fixedly connected to the left side of the sealing plate 8122, and the other end of the connecting hose 8123 is fixedly connected to the mounting tube 86.

[0026] Reference Figure 2 , 6 As shown, the inner wall of the scanner box 6 is fixedly connected with a data analyzer 9, the inner wall of the left cavity of the installation box 5 is respectively fixedly connected with a controller 11 and a wireless signal transmitter 12, an air outlet 13 is provided on the back of the installation box 5, the data analyzer 9 and the laser scanner 7 are electrically connected, the data is fed back to the data analyzer 9 through the laser scanner 7, and the signal is further transmitted to the computer controlled by the measurement personnel through the controller 11 and the wireless signal transmitter 12, which is convenient for use.

[0029] When the intelligent laser scanning device for building structure mapping is working, the tripod bracket 2 is first opened to stabilize the device, and then the controller 11 starts the laser scanner 7 and scans the building structure, and further starts the driving motor 81, and the driving motor 81 drives the driving rod 82 and the driving wheel 84 to rotate, and then the driving wheel 84 drives the transmission belt 85 to rotate, and then the transmission belt 85 drives the driven wheel 89 to rotate, and further the driven wheel 89 drives the rotating shaft 88 and the fan blade 810 to rotate and suck the air outside the device into the installation pipe 86, and then the air After flowing to the connecting hose 8123 through the installation pipe 86, it is continuously discharged through the air outlet pipe 8124. At this time, the steering motor 8125 works and drives the driving frame 8126 to rotate along the output shaft of the steering motor 8125, thereby changing the air outlet direction of the air outlet pipe 8124. Then, the air contacts the heat absorbing fins 10 and absorbs the heat, and then is discharged through the exhaust hole 14. Then, the air that absorbs the heat flows through the exhaust hole 14 to the left cavity of the installation box 5. Since the outside air continuously flows to the inside of the installation box 5, the hot air is then discharged from the inside of the device through the air outlet 13. If the scanner box 6 needs to be rotated up and down, the controller 11 controls the electric telescopic rod 838 to move, and after further moving the driving lever 837, the switching tube 832 follows the driving lever 837 to move to the left, and the driving block 1 833 and the driving block 2 834 follow the switching tube 832 to move to the left, and then the driving block 2 834 moves to the inside of the positioning groove 836.

If the scanner box 6 needs to rotate horizontally, the motor 3 is adjusted to drive and drive the fixing block 4, so that the installation box 5 and the scanner box 6 rotate as a whole; When the scanner box 6 rotates, since the sealing plate 8122 is fixed, the sealing plate 8122 and the scanner box 6 make relative movement, and the moving trajectory of the sealing plate 8122 is to make relative rotational movement with the central axis of the rotating rod 835 as the midpoint, so that the subsequent heat dissipation mechanism 8 can continuously input air to the scanner box 6, and when the steering motor 8125 rotates with the scanner box 6, the connecting hose 8123 is set so that the air outlet duct 8124, the drive frame 8126 and the steering motor 8125 can still work normally.
